Option # 4 sets the throttle ID of your throttle. Each throttle in your LocoNet system can have its own unique ID to support advanced LocoNet functionality. Products that use this feature will usually require each throttle in your system to have a unique ID.We recommend changing this ID only when specifically directed to do so by the manufacturer of a LocoNet compatible product that requires unique throttle IDs for operation. You may use any ID in the range of values x00-x7F (hex) and you must be sure that every throttle in your system has a unique ID #.

What is the difference between programing on the layout using Track A and B and using a dedicated programing track using Pgm A & B. Is there a difference in voltage, packets, protocol between the two? Programming Track Broadcast programming, also called service mode programming, uses a programming track. The programming track is electrically separate from the rest of the railroad, and is connected to the "PROG A" and "PROG B" terminals of your DCS100/200 or Zephyr (Xtra) command station.One major advantage to a programming track is that many systems can read-back the Configuration Variables (CV's) that are in ...

Editor's Note: This tech note has nothing to do with Digitrax SoundFX sound decoders. This is for users who have Digitrax command stations / boosters / etc and wish to program MRC sound decoders. --------------------------- Due to low programming track power in certain dcc systems, programming sound decoders on the program track may not be possible, especially trying to assign the decoder a four, (4), digit address. This programming procedure has to be performed on the mainline, where more power is available for programming sound decoders. If your dcc system allows simple 4 digit address programming on the main, [ops mode ...

Q: Can you have two command stations on the same layout? A: No. If you try and run with two command stations you will experience what we usually refer to as "shocking, horrifying results." Two command stations on a single layout is often a problem with modular layouts. You can disable the command station capability in Digitrax Command Station/Boosters so that you can use them as boosters only to add more power to your layout.For the DCS100 to disable command station mode:1. Set Op switch 2 to "c" 2. Set Op switch 5 to "t" 3. Set it to auto ...

Q: Can I assume that any of the 3 powering options for the DS64 are acceptable for OpSw changes? A: Yes you can power the DS64 using any of the 3 options. The DS64 is strictly looking for power, and doesn't need the DCC signal from the track to set op-switches. Q: If I have only 3 turnouts on a DS64, to complete the 4 point programming I have been inputting a bogus turnout number. Is that correct? A: Yes, that is correct. Q: When setting OpSw 1, do I have to be connected to track power or can I power ...

A slot is a memory location in the command station that holds an active decoder address. The number of slots is the number of locomotives that the command station can support in operation at a time. When the available slots are filled with decoder addresses, trying to select another locomotive address to run generates the "slot=max" error code. When all the slots are full you can't select another address until one is released from the system. See Clearing your Command Station's Mobile Decoder Slots below for how to prevent this from happening.The DCS100 Command Station/Booster that is included with Super Chief Xtra and other ...

Ops Mode programming, also known as "Programming on the Main" lets you change the configuration of an individual decoder while the locomotive is on your railroad without having to move it to the programming track.Operations mode programming lets you program CVs in DCC locomotives equipped with Ops mode capable decoders while they are on the mainline. A typical use for Ops mode programming would be to change the acceleration rate (CV03) or the deceleration rate (CV04) of your locomotives to simulate the weight and braking capability of the train to compensate for changing the number of cars or power units on a ...

Operations mode (OPs mode) programming allows you to program decoders on the layout instead of having to move them to a separate programming track. This is a write only programming method. If you want to be able to read back the values written to a particular decoder using Ops Mode programming, you will need to install transponding on the layout. If transponding is not active on the layout, you must use an isolated programming track for reading back CV values.The extent of the area with OPs Mode readback available depends on how muchof the layout is instrumented for transponding. The ...

Programming On The Mainline: Operations Mode ProgrammingOperations Mode Programming [Ops Mode] lets you program CVs in DCC locomotives equipped with Extended Packet Format decoders while they are on the mainline. This is handy for situations where you want to make an adjustment to a specific locomotive while it is in service. There are also situations where mobile decoders from other manufacturers can only be programmed in this manner. A typical use for Ops mode programming would be to change the acceleration rate (CV03) or the deceleration rate (CV04) of your locomotives to simulate the weight and braking capability of the ...

Q: What is the basic configuration and OpSw settings for a section of the PM42 when configured for circuit breaker control? A: The PM42 is a 4 section multi-purpose device where each of the four sections can be individually configured to act as either a circuit breaker, or automatic reverse loop controller. The PM42 monitors the current flow to the rails and interrupts the connection when it senses that the current demands exceed the upper allowable current level determined by the User controllable Option Switch (OpSw) settings. The power flow of a layout's command control system starts with the command station, or ...

Q: How can I write and read the Configuration Variables of Mobile Decoder on the mainline using the DT40x Throttle? A: Operations Mode Programming, also known as Ops Mode, lets you program a locomotive decoder's CVs while it is on the main line. With the addition of transponding in Ops Mode, you can write and read back CVs in DCC locomotives equipped with most modern decoders while they are on the mainline. Some older decoders before Extended Packet Format was used are not able to do this.For example: A typical use for Ops mode programming would be to adjust an engines ...

If you want to change the address or other settings of your locomotive decoders, you must set up a programming track. It is very important that the rest of your railroad can be isolated from the DB150 and the programming track when you are programming a locomotive. Decoders are programmed when the DB150 command station sends programming information to them through the rails. There are two basic ways of programming decoders. Service mode programming broadcasts a message to all DCC equipped locos that are on the track. Because this is a broadcast method, you will need to set up a ...

There is no way to completely reset the Digitrax DCS100 or DCS200 Command Station/Booster using Option Switches such as Option Switch 39. Option Switch 39 resets Locomotive Registry, Consists, etc. associated with DCC equipped locos by resetting mobile decoder info (that is in the command station) and consists, routes and loco roster info. It does not necessarily reset other Option Switches as expected. A complete reset of the DCS100 and DCS200 to factiory defaults is only accomplished by removing input power and removing the battery. This involves disconnecting the grey terminal plug then removing the metal cover by unscrewing the ...

Q: If my layout is experiencing short because of a thrown switch, how can you reset the switch using DCC? Many Digitrax operators use the PM42 Power Manager, which provides protection to four power sub-districts. One segment of the PM42 is used to control track switch power, with the balance being used for train power. When the inevitable happens and a train runs into a thrown switch, resulting in a short, the PM42 shuts down the track power in that segment, while the track switch power is maintained, allowing you to throw the offending switch. Because the PM42 isolates only ...

Trains run on two rail track. When a train needs to change to a different or diverging track a track feature called a turnout, switch, track switch, points, frog or other name comes in to play. The function of this track feature is to move the rails so that the train can change tracks. When the turnout is "closed" the train will go straight through and when it is "thrown" it will go on the diverging track. Railroad employees in North America call this track feature a switch. They call the moving parts of the switch the points. They ...

The slip switch is a track element that has both a crossing at grade and also a set of movable points which allow trains to both cross another track and also change track. The Crossing The crossing allows tracks to cross each other at grade. The Slip SwitchThe more complex slip switch allows trains to both cross and to change tracks: In the schematic below, you will note that the slip switch is more compact than ordinary turnouts. As a result, they are often found in high track density areas such as passenger terminals, where space is at a premium. ...

Overview: Broadway Limited has issued a new line of H0-Scale locomotives called "Blueline". These locomotives are equipped with sound decoders that can be operated in a conventional Direct Current environment. They also are fitted with an 8-pin DCC Medium plug to allow for conversion to a DCC operating environment. Among other decoders, Broadway Limited recommends using our DN143IP mobile decoder for this purpose. Converting these locomotives is simple, but programming a 4 digit address can be a challenge. BLI has a support page which indicates that changing the locomotive address and other CV's can be done in OPS Mode (also ...

Ops mode programming is the only programming method that will work while the DT400R simplex is operating as a radio throttle. If you press the PROG Key to enter programming mode, the DT400R running as tetherless will default to the Po mode (ops mode programming). The DT400R must be connected to LocoNet to use service mode programming and access any of the other programming modes available.

Duplex Radio Throttle do not need to be plugged in to LocoNet to Program Decoders. Simplex Radio & Infrared throttles must be plugged in to LocoNet to program CVs on the programming track. Ops Mode Programming can be done without plugging radio throttles in to LocoNet. IR throttles must be plugged in for Ops Mode Programming. 1. Be sure that only the loco you want to program is on the programming track. If you are using operations mode programming, the loco you want to program can be anywhere on the layout but it must have a decoder that is ...

Two Programming Methods Are Supported by Digitrax Command Stations:Service Mode Programming is done on an electrically isolated programming track. Using this mode, the command station broadcasts programming information to all decoders on the program track. Within Service Mode programming are Paged, Direct and Physical Mode.Because these are a broadcast modes, we must isolate the decoder we want to program from the others on the layout by using a separate programming track that is connected to the command station for programming but not powered for operation of the locomotive. This mode works with all DCC decoders. This is the most commonly ...

The option switches and settings you can use to customize your BDL168 are indicated in the table below. These option switches on your BDL168 are set up using a Digitrax throttle's SWITCH commands. (This can only be done with a Digitrax LocoNet throttle or equivalent software). SWITCH mode is normally used for operating turnouts by issuing closed ("c") or thrown ("t") commands. In the case of your BDL168, each switch address is a BDL168 option switch. The following table shows what each OpSw is used for when it is set for thrown or closed. Factory settings are indicated by shaded ...

Switch Mode is used for sending commands to accessory decoders and for changing Option Switches (OpSw) in your DCS50. The most common use of switch mode is for operating turnouts (track switches).To change the position of a turnout:This note assumes that you have already installed and programmed turnouts and turnout decoders on your layout. Each turnout is connected to a stationary decoder that controls the operation of that turnout. There are several different stationary decoders for this purpose such as DS64 and others. Please see the related articles below.1. Press the SWITCH Key. 2. The last switch address selected by ...

I have my Kato Switches hooked up to a standard switch panel with toggle momentary switches. Can I hook up the DS51K1 stationary decoder in addition to this wiring? In other words, if hooked up the DS51K1 to the Kato Switch Machine that was already wired to another source to throw the switch, would the momentary power damage the decoder when it is operated by the standard control panel? I would like to operate these switches via DCC and by the control panel. In this situation, it would appear that using a DS64 configured for Kato turnouts (solenoid turnouts) and ...

You can automate grade crossing signal lights with block occupancy sensors. Install a BD4 to detect track occupancy as shown in the figure below. Other than removing the Op Sw35 commands from the routes used in the related article example, there is no additional programming needed for the DS64. Sensor operated occupancy detection requires that all rolling stock be equipped with resistor wheels for proper detection or that the detection section is longer on each side of the RR Crossing than the full length of a train since only the locomotive will draw current. A lighted caboose on the end of ...

If I use a non-Digitrax compatible system, what features of the PM42 Auto reverse/Short Circuit Managers (SCM) will I lose?The PM42 can be used as a stand alone Auto reversing unit and Short Circuit Manager with many other non-Digitrax systems, but for systems without LocoNet capability a number of networked management features will not be available.For example, the PM42 sends out real-time, event driven (non-polled) information to the LocoNet about fault problems and resolution, auto reverse actions and also identifies the affected sub-districts. This allows other devices, such as PCs, the Digitrax Signaling system, Digitrax Transponding or other detection and ...

Why does the DS64 generate multiple output pulses for a single command? I get between 2 and 5 pulses over a period of about 2 seconds. Option Switch 01 determines the type of turnouts that you can operate, static or pulse. The Factory default is for "Pulse". Option Switches 02, 03, 04, and 05 set the pulse length. OpSw 02 = Closed the pulse width is 200ms (milliseconds). OpSw 03 = Closed, the pulse width is 400ms. OpSw 04 = Closed, the pulse width is 800ms. OpSw 05 = Closed, the pulse width is 1600ms. All, or any combination of ...

Once you have set up the DS64 to operate the type of turnouts you will use, the next step is to hook up the turnouts to the outputs of the DS64. Each type of turnout machine has specific requirements for wiring.Note: The DS64 is configured for either for solenoid turnouts (the default setting) OR slow motion turnouts. Only one type of turnout motor can be used on any particular DS64.Note: Multiple turnout machines can be operated on a single DS64 output.For example, you can run 2 Peco or Atlas Snap Switches on a single DS64 output. Up to 4 Kato ...

Q: I am setting up a yard control panel with a CML Electronics DTM30. For the DTM30 to know what state a turnout is in, it can issue an interrogate command but my DS54's do not seem to respond with this information. Is there a trick to this? A: According to CML: The DTM30 makes use of the “Interrogate” feature that all modern Digitrax systems use. After power up, the Command station normally sends out 8 switch commands. All accessory devices respond to these, and send LocoNet messages back reporting sensor states and point states. The DTM30 can also send ...

Some Digitrax decoders offer scalable speed stabilization (also called back EMF) control to help smooth out operation in the low end of the speed range. This feature can be beneficial especially in N scale switching situations especially when the decoder can select how much of this effect to implement (scalable speed stabilization). Speed stabilization is a decoder feature that can be used with any DCC system. Most Digitrax decoders that support this feature are shipped with scalable speed stabilization turned off so, to use it you will need to set program them to use this feature. Other Digitrax decoders are ...

Q: Can I use a PM42 with a non-Digitrax DCC Command system? A: The PM42 was specifically designed to work with Digitrax Direct Home wired layouts. Any system that is configured this way will probably work with the PM42 with no interoperability issues. Digitrax has no control over or knowledge of each specific non-Digitrax system and how it may interact with the PM42. The PM42 can be used as a stand-alone auto-reversing unit and short circuit manager with many third party DCC systems, but for systems without LocoNet capability a number of the networked management features will not be available. ...

At first glance, the typical switching railroad would not seem to be a good candidate for DCC operations. Yes, there may be only one locomotive on many of these railroads, but that locomotive can still benefit from DCC. By adjusting the starting, mid-range and maximum speed values of this locomotive, you get very good slow speed control, perfect for the switching railroad. And, of course, if you add a second locomotive, then DCC becomes the clear choice because you are not longer having to throw toggle switches just to move around the yard. The DCC environment also gives you turnout ...

On Page 9 of the instructions (under 5.0 Op Sw Set Up) I am to connect my DT400 throttle to my powered PM42 . . . 1. Does “powered” mean having the PS-14 power supply to the PM42 connected and energized? Yes. We took another look at the documentation and it means that the PM42 should be operating with its own power supply. What you are doing is using the DT400 to program the internal controls of the PM42; to do so would require that the PM42 be in its operating state, thus the power supply. The DT400 is merely ...

Q: My Atlas DCC N-Scale locomotives that are equipped with factory installed Lenz062xf, Lenz063xf or 'new' Atlas decoders will not program using the DCS50 in any mode, either on the OPS track or Program track. I know the system works because I can easily program every Digitrax decoder loco that I have, but if I put an Atlas DCC factory loco on the programming track I get the 'd nd' error code There are decod

If you have trouble reading back CV's on the programming track, this may be due to insufficient current draw on the SFX064D function leads. You can always just re-program the CV value into a CV to get the desired results, even though reading CVs does not work. OPs mode is recommended for programming all CVs except CV01, CV17 & CV18 (2 digit and 4 digit addresses). If a second DCC decoder is present that is not Sound FX compatible then correct readback of CV data is not possible, since the NMRA CV readback was not designed for multiple decoder readback.

The DB200+ is the 8 amp booster. It has NO command station capability. This booster was designed for adding power to layouts that run lots of locos and for large-scale layouts where power requirements are heavy.DB200+ Control PanelNOTE: DB200+ front panel graphics may vary from those shown here. Internally the booster is the same. These instructions are written for both versions of graphics as well as the DB200+ OPTO optoisolated version of the booster.

How do I get all the engines of a consist to run at the same speed? I have 3 engines with DH163A0 decoders and one with a MRC sound decoder. All units have the same top speed, but the unit with the MRC decoder starts and accelerates more quickly. Getting a group of locomotives to operate at the same speed can be a challenge. Experience has proven that it is best to work with the slowest locomotive and bring the other locomotives into agreement with that engine. Since the others appear to be in general agreement, it would be the ...

The Mode Switch: The Mode Switch next to the Green LED is used to toggle back and forth between MS-100 mode and PR2 Programmer Mode. The Green LED will wink once per second if in the MS-100 Mode or toggle every second when in the PR2 sound programming mode. The Loconet Termination Switch: The switch next to the error LED is used only in MS-100 mode to activate the Loconet current source termination feature. This switch is active ONLY when a command station is NOT connected to the Loconet and the red LED is solid on indicating there is no ...

The SWCH Key is used for entering switch control mode. Once this key is pressed, you will be prompted to select a switch address and issue a thrown or closed command. Switch control mode is used in normal operation for operating turnout machines and in set up mode for setting up option switches in the throttle and command station.

To reset the DCS51/DCS50 to factory settings: If you change command station option switches and experience unexpected results, just set OpSw 39 to “c” (closed) to reset the unit to the original factory settings. 1. Press the PROG key. The display shows the last decoder programming mode used. 2. Press the SWITCH key. The display shows the last switch used and its commanded position. 3. Use the numeric keypad to enter the number of the Option Switch you want to change; in this case 39. 4. Press the "c - / CV-WR (lower right of keypad)" key to set the ...

Q: Is it possible to use Digitrax equipment to wire the Kato N-Scale Automatic Track Crossing? If so, how do I do it? A: The answer is a probable "No", but there may be a workaround. The Kato, USA website notes: Some Unitrack components such as the Automatic Crossing Gate and 3-Color Signal were designed with DC operation only. So, the official position is that that these devices don't work in the DCC environment. However, we are not above speculating on how to do this, nor are others. An online web search turned up this bit of message traffic by ...

DCC Automatic Reversing SectionsVirtually all automatic reversing will fall into 3 categories with the wiring principles for all being the same:1. Reverse Loops2. Wyes3. TurntablesDCC has the ability to automatically reverse sections of track we call Reversing Sections while our trains are running and not affect the direction or speed of the trains. This is because we put a constant square wave AC current on the track and control the trains (locos) by sending messages to them (actually to receivers we call decoders) to tell them what to do such as start, stop, change directions, etc. . We are thus ...

Setting up DS54 for Exact Turnout Reporting The creation of a feedback circuit for exact turnout reporting is simple. Connect a normally open set of contacts attached to the switch machine, a normally open set of contacts of a micro switch monitoring the throw arm, or a normally set of contacts of a relay monitoring the switch machine power to the common and switch input of the DS54 input connector. When the turnout is closed these contacts must be closed. Connect a normally open set of contacts attached to the switch machine, a normally open set of contacts of a ...

How To Set Up Routes Using Your DS64NOTE: During this procedure the DS64 must be connected to an active LocoNet with an active command station.1. Press and hold down the STAT button on your DS64 until the green LED begins to blink quickly. You are now ready to set up a Route.2. To program the DS64 Route Number, use your DCC throttle in Switch mode to select a Switch Address from 1 through 8 and issue a Closed or Thrown command. This lets the DS64 know which of the 8 available routes you are setting up. This is NOT the ...

Can I convert my DCS100 to a booster. I cannot find the switches in the instructions to accomplish this. Is it too old?. Can I return it for repair to accomplish converting it to a booster? The DCS100 is already a booster combined with a command station, but it can be converted to act as an expansion booster by using option switch 2 (OpSw02).

The 5 Amp DCS100 and the 8 Amp DCS200 share the same front panel layout. There is a variety of indicators, switches and connectors: Power Input The two POWER IN terminals on all Digitrax boosters & command stations are the power input connections. Power On Indicator This green LED indicates that the power to the DCS100 is on. Ground Terminal The terminal marked ground provides electrical safety features and an RF ground reference for minimum radiated noise. This should be the ONLY point of any DCS100 installation that is connected to the AC safety ground pin provided on most 3 ...

When you are finished running a locomotive address, you should release it from your throttle so that the locomotive address is available for other throttles to select and run. This also clears a slot for a different address to be used in the system.Radio and infrared throttles must be plugged in to LocoNet to release an address from your throttle. You can disable this safety feature by setting your DT300’s OP#3 to one of the values that allows tetherless release. To release an address from a throttle:1. Use the THROTTLE knob to select the loco and make its speed zero. This step ...

The BDL168 is designed to be used with power management devices such as PM42. The BDL168 is designed to operate “downstream” of the Digitrax boosters and power management devices. The BDL168 is the "last" device in the chain from booster to power manager to BDL168. It is connected directly to the track detection section. There should be no other connections to any detection section that will draw track power or the detection section will always show occupied. If a device is used to switch off power feeding the BDL168 and the track it is connected to, for example, a PM42 ...

The DN142 comes from the factory with BACK EMF SPEED STABILIZATION (BEMF) turned off. Follow this procedure to turn it on and to adjust it. Later generations of Digitrax mobile decoders do not require this procedure. Activation: To activate the BEMF feature, change CV57 to a value of 06. This will give good performance with most brands of locomotives. If the locomotive surges while using BEMF use a lower value for CV56. It may also be necessary to adjust CV's 55, 56, & 57 to get the motor performance desired for your particular locomotive. Adjustment: 1. Program CV57 (Droop control) ...

In earlier generations of model railroading, the reverse loop (reversing section) was the bane of many model railroaders. As the rails of a track come back upon themselves, an electrical short circuit is created. In the analog control world, the solution is to use toggle switches and special wiring to allow the locomotive to move on to the next block. Electromechanical solutions relying on relays and track detectors can also be used to automate reversing on an analog layout. The wye is another example of a reversing section on a layout. One of the advantages of digital command control is ...

How do I Increase BDL162 Detection Section Threshold SensitivityThe BDL162 has Option Switch settings to control detection sensitivity. The factory setting is OpSw19=t for a threshold sense for DCC occupancy of approximately 22 Kohms minimum. Changing OpSw19=c will set the threshold to 10 Kohm minimum. See the BDL162 instruction manual for details on setting the Option Switches. These settings will accommodate most layouts, though there may be circumstances when a higher threshold is desired, for example, in a high moisture environment or with G scale operations outside.To raise the threshold even further resistors can be added into the wiring between ...

Q: I have read in some of the model magazines that the F2 button on the DT400 is a pressure sensitive playable whistle button. I have not noticed any difference in sound with the F2 button on my DT400. Is there some way to determine if this feature is present on my throttle? A: Most Digitrax DT400 and all DT402 series throttles have the capability of implementing the playable whistle feature when used with Digitrax sound decoders.Prior to the release of Digitrax sound decoders this feature was considered as an experimental throttle feature and was not fully documented. Once Digitrax released ...

Digitrax SoundFX lets you make your locos sound like the real thing!Remember, your Digitrax SoundFX decoder is ready to run and will operate and generate sound using address 03 with no additional programming.On your Digitrax system, simply select the locomotive's address and the sound will start. On some DCC systems, it is necessary to select the locomotive address AND send a command to start the sounds. When used in conjunction with a separate DCC motor decoder in a single locomotive it is most practical to program both decoders to the same address and operating modes.For a more prototypical railroading experience, ...

Direct Home Layout Wiring Digitrax strongly recommends direct home wiring where each power district and its booster are electrically isolated. This method of wiring has safety advantages and makes troubleshooting problems easier. In addition, direct home wiring makes detection work more prototypically. With direct home wiring, the BDL168 can determine and indicate whether any of its 4 zones is powered or not (possibly short-circuited) even when there is nothing on the rails in the detection sections. The BDL168 factory-set logic causes the detection sections to show "occupied" if the associated zone's power is off (because in this case, detection is ...

Q: Can I set up the DS54 to act as an emergnecy stop device? A: Any unused DS54 input can be configured to send an Emergency (OPC_IDLE) Stop packet. The typical Emergency Stop circuit is a supervised series of one, or more, normally closed switches or contacts. When any one of these devices is opened the circuit is deactivated and everything affected by the Emergency Stop circuit immediately shuts down. The following drawing depicts a typical Emergency Stop circuit using a DS54.

QUICK INSTALLATION Notes for users with decoders not made by Digitrax:1. The DCS50 command station operates in 128 speed step mode. If you are using a locomotive with a decoder that does not have 128 step capability you will have to adjust either the decoder or the DCS50 so that both are using the same number of speed steps to communicate. We call this procedure status editing. You can status edit each individual decoder or you can change the DCS50’s system default by setting the DCS50’s Option Switches 21-23 and run all of your decoders with fewer speed steps to ...

Dispatching is a special way of offering a locomotive address to a UT1 or UT2 to run. The address is set up and then dispatched to the system to be acquired by the next throttle that presses its ACQUIRE Key. This is not the same as releasing a locomotive address from the system. Releasing an address clears it from the locomotive slot to make room for another locomotive address to be run by the command station. 1. Set the address selector switches to address “99” then press the “ACQ” button. 2. The Status LED will light green showing that you ...

This section discusses the installation of the physical wiring of the Texas & Southwestern. Underneath the completed Texas & Southwestern are various wires and cables which allow you to operate your railroad. Initially, seeing all these wires can be intimidating, but as you will note, they have been grouped and bundled so that identifying the individual wires is easy. There are two groups of wires under the railroad; one group, the power bus, delivers power to the tracks and to the stationary decoders that operate the track switches. The other group of wires is the black cable for LocoNet and ...

The STOP key has two uses: as an emergency stop for the locos on the layout and as a shift key used in conjunction with other keys.Emergency Stop keyThe factory setting for the STOP key is for Local Emergency Stop which stops just the locos controlled by the two throttle knobs on the DT300. The STOP key can also be set for Global Emergency Stop which will stop all of the locos on the layout. This is done by setting throttle option switches.Using the Stop key as a Shift KeyThe STOP key is also used as a shift key in ...

Braking sections are sections of track which will cause a DCC equipped locomotive to stop automatically. The simplest way to do this is to set up a track section where the power is turned off. This has two disadvantages. First, since there is no power, the locomotive lights will be off when the train is stopped in the section. Second, the lead loco in a consist stops as soon as it hits the dead section. Other locos in the consist will push the dead loco forward. In a long consist, you could get a situation where the last loco in ...

This H0-scale railroad track plan first appeared in the Atlas Model Railroad Company's book "Six Railroads You Can Build", written by John Armstrong and illustrated by Tad Stepek. This book was first published in 1958 and has been reprinted several times. A classic bowl of spaghetti, the Transbay Interwoven has two reversing loops and a turntable. DC Control For DC operation, Atlas specified three Atlas Controllers (for the reverse loops and the turntable), two Atlas Selectors (to control eight track segments) and ten controllers for the railroad's turnouts. DCC Makes Things Simple With DCC, the wiring of this railroad is ...

Function or “Fn” mode is the default mode for the DT402 & DT400 throttles because it is the mode that runs your trains.In Fn mode, the throttle knobs, reverse direction keys and Y+/N- keys are used to control locos. The numeric keypad is used to access functions for the currently active loco address. In Sw Mode, the keypad is used to operate track switches. This means that you can continue to control your trains while turning on and off functions and operating turnouts.If a throttle has a locomotive address selected, the associated loco icon and direction indicator will be lit. In ...

In addition to the locomotive address, there are different Configuration Variables (CV's) that have been defined to handle many characteristics you might want to use for your locomotives. These include operational characteristics such as acceleration, headlight functions and others. The manual for each decoder type has a complete listing of CVs that are available in specific decoders, what they do and the suggested values for each CV. Simpler decoders have few CVs while advanced decoders may have many different CVs 1. Place the decoder equipped locomotive you want to program on the programming track If you are using operations mode ...

Use a throttle to change the PM42's Option Switches 01, 02 and 09 as detailed in the PM42 instruction manual. The PM42's trip current threshold can be set at a value from 1.5amps to 12 amps. Always use the lowest possible setting, consistent with good operation and reliable short circuit detection and recovery. Higher current settings are not "better." We ship the PM42 with a moderate current trip threshold of 3amps so it will work on most DCC boosters and layouts with no changes.This is because some boosters cannot supply enough current with the track feeder resistance to reliably allow ...

Many clubs use a DCS100/200 as a Booster in their setups. Digitrax does not recommend using a DCS100/200 as a Booster only for this type of setup. If you decide to do so, please keep this information in mind: The DCS100/200 configuration is stored in memory that uses a CR2032 battery. Over time the battery can get weak and the DCS100/200 will loose its ability to store its configuration. When this happens, the DCS100/200 will sound 7 beeps at power up. It will also revert back to its factory settings and once again become a Command Station. Since LocoNet ...

What do I need for DCC control of a Walters Cornerstone Swing bridge? Image Courtesy Wm. K. Walthers We do not have any direct experience with this particular bridge but after a little research, this is what we recommend.The instruction sheet which comes with the 933-1050 Motorizing Kit is quite vague. "The unit runs on DC power. Hook the wires up to the DC contacts on a transformer with a maximum voltage of 12. If you hook it up to a variable speed transformer, do not exceed 12 volts. The gear ratio is 320:1." That said, it is still a ...

My PM42s seem to correctly trip on track shorts and auto-reverse reliably, but the power briefly drops out during these events, and when the PM42s attempt a fault recovery into a persistent short circuit, why is this?No power on earth can stop the track voltage of the booster from collapsing to a low value when a true short circuit is present. This is simply Ohm’s law in action!Actual track voltage seen depends on: the loop resistance of the short circuit, the current capacity of the booster and power supply and whether the Booster employs "smart" fault detection and recovery along ...

As originally conceived, the Texas & Southwestern was set up with a very simple DCC system. The railroad uses a DCS50 Zephyr as its command station and booster. The Zephyr is connected to a central power bus, and all tracks, stationary turnout decoders and the automated reverse loop unit are connected to it. Likewise, the LocoNet connections are a series of simple cable connections starting at the Zephyr and ending at the last Universal Panel. The T&SW works well with this arrangement, but there are additional devices that will enhance the operation of this railroad. Digitrax PM42 Power Management System ...

Programming is the process of setting the configuration variables (CVs) in your decoder to the appropriate values that will make the locomotive perform the way you want it to. The first CVs that most people change are those that set the locomotive decoder's address. The mobile decoder in your locomotive usually comes pre-porgrammed to a factory default address of "03". Once you add a second locomotive, you will want to change the this new locomotive to another address. Not doing so will result in both locomotives operating at the same time when you send commands to address 03.Likewise, there are a ...

Over the years, different Digitrax throttles have used a combination of decimal, modified hexadecimal and hexadecimal numbers for entering CV numbers and CV values. The following information is provided as a programming reference to show you how these different schemes work so that you will be able to use your throttle to program decoders.UT1 & UT2 Utility Throttles use decimal numbers exclusively for CV numbers and CV values. Because these throttles use 2 selector switches that can access the numbers 0-9, you are limited to programming only CV#s and values from 00 to 99.DT100 Throttles use a modified hex numbering ...

Q: Your recommendation is to have a DB150 booster at no more than 50 foot intervals. Will one booster handle all track in that 50 foot area, i.e. a passenger terminal throat with many turnouts and switches? A: The "50 foot intervals" applies to the maximum distance which boosters can be located from each other. This is a conservative recommendation. You should consider how much power will be consumed in a district when locating boosters around the layout. If your power district is a single track railroad stretching over hundreds of feet of linear distance, boosters should be placed at 50 ...

There are many different CVs that have been defined to control operating characteristics of your locomotives.

Q: Using Digitrax systems to program an MRC AD310 decoder is especially confusing because the MRC Command 2000 uses several "switches" and "levers" rather than standard CV numbers. A conversion chart for the 10 possible MRC engine addresses would be a wonderful help to us old-timers. A: The documentation available from the manufacturer of this decoder is incomplete. Many older decoders such as this one are not able to recognize all the digital packets in use by more modern DCC Systems. What we have learned is the MRC AD310 is: Programmable up to 127 (1~127) locomotive addresses Programmable for either 28 or ...

Common Rail Wiring Many older model railroads use Common Rail wiring because they were initially wired to operate with electrical toggle switches. Conversion to DCC is possible with Common Rail, but it is not recommended. Whole layout common rail is a method of wiring layouts where power districts and their boosters are electrically connected using a common rail or common power bus return wire. Whole layout common rail wiring is a disadvantage when it comes to detection systems since detectors cannot independently monitor whether zone power is on or off so they can't tell whether occupancy detection is working in ...

Digital Command Control (DCC) has specific electrical requirements that must be provided for your layout control system to operate properly.Input PowerAll DCC systems require an external power supply. Digitrax manufactures several power supplies for our command stations and boosters: The 3 Amp PS415 (the Zephyr Xtra power supply) The 5 Amp PS515 for all Digitrax 5 amp command stations and boosters The powerful 20 Amp PS2012 can be used for multiple 5 and 8 amp command stations and boosters Additionally, the PS14 is available to power various other devices for your railroad. Digitrax strongly encourages you to use our power supplies to insure satisfactory ...

I'm helping a friend rewire an existing layout from analog to digital. You might be familiar with the layout, it is the original Clinchfield layout that Model Railroader built back in the late seventies, believe it or not. The layout, of course, is blocked for analog through DPDT switches which have been eliminated. I was able to repair the wiring back to original using the drawings that MR printed. The layout uses common rail wiring, this is what I have to work with, and to rewire using home run wiring would be a MAJOR rework, not doable. I was able ...

The term smooth DC is used to describe the power provided to the layout by conventional model railroad power packs (analog transformers). Traditional model railroad power packs convert household line current into 12-18 volt current to power your model railroad. Voltage is supplied to the track, and as the voltage increases, the speed of the locomotive's motor increases, which makes it run down the tracks at faster speeds. Some power packs put out only AC (alternating current), while others put out DC (direct current) and AC (for accessories such as track switches and building lights). AC powered trains tend to ...

Power Management is a concern on every layout. With Digital Command Control, the main concern is that enough power is supplied to evey track section on the layout so that the digital signal is transmitted to the decoders in the locomotives and turnouts.Each locomotive uses power from the track, some for the motor, some for headlights and other functions and some for the command control electronics in each locomotive. More electrical power is necessary to run more locomotives on the layout. Digitrax boosters provide between 2.5 amps & 8.0 amps. A small N Scale or HO Scale layout with two to ...

The Kelana Jaya Rail Line model layout uses WinLok 2.1 running on a PC under Windows 98 to operate the trains, turnouts, signals and to use the feedback from the block detectors for train control. This equipment was configured and programmed to PUTRA's specifications by Dr. Hans R. Tanner of DigiToys Systems. PUTRA specified the following capabilities for the control system used for the simulation: 1. Run eight trains at once in any combination of automated or manual control. 2. Define specific routings and be able to assign automatically or manually any route to any train at the time the ...

Here are some terms that you might find useful as you work with the BDL168. Direct home wiring is a layout wiring method where each power district and its booster is electrically isolated. The track within each power district uses a "common return" wiring method for occupancy detection and/or power management. Direct home wiring is the wiring method recommended by Digitrax for safety reasons & also because it makes detection work more prototypically. Power district is the power wiring, track, components and equipment attached to that wiring, driven by a single properly isolated booster. The track for a power district ...

PM42 Short Circuit/Auto-Reversing Failure When used with Zephyr (DCS50) The PM42 is designed to control 4 independent power subdistricts that can be set up as either a “Short Circuit Manager” (the factory setting) or as an “Auto-Reversing Controller.” The PM42 factory setting for trip current is 3 amps. The trip current can be modified to settings from 1.5 amps – 12 amps to accommodate the needs of your system. In addition, each of the 4 power subdistricts can be set for slow, regular, faster or fastest short circuit management. While a trip current of 3 amps will work with most ...

I have an "M" shaped 250 square foot layout with 500 feet of track and twelve locomotives. What Digitrax equipment would I need? You don't say what scale this railroad will be modeled in, which is important since the locomotives in smaller scales draw less current than larger decoders. However, for purposes of estimation: Twelve Locomotives. Each locomotive is going to draw, at the very least, 5 MA for the decoder. If it has LED lights, then it will typically draw 15 MA more; conventional light bulbs will draw 50 MA. A typical H0 locomotive will draw 600 MA ...

LocoNet is Digitrax's method of communication between LocoNet compatible devices on a model railroad layout. LocoNet compatible devices are designed to work together on the network, and in some cases can also accept DCC commands from the track, but often go beyond the scope of simple DCC train control. LocoNet is a peer-to-peer Ethernet type multiple access network. Because of its design architecture, it is very robust and powerful. Layout implementation is simple and wiring is free form with minimal limits. LocoNet is designed to run an unshielded 6 conductor ribbon cable. Digitrax recommends using flat, six-conductor telephone wire ...

Digitrax Complete Train Control By Zana & A.J. Ireland Digitrax Complete Train Control makes reliable, realistic train operation and simplified layout wiring a reality. Digital Command Control is incorporated within the Digitrax system to let you control multiple trains independently on the same section of track without blocking. In the real world, engineers control the speed and direction of real trains. Engines operate under their own power independent of the track. Each engine has its own motion characteristics like how fast it speeds up (acceleration) and how long it takes to slow down (deceleration). A locomotive's performance is influenced by ...

Speed stabilization is a feature that causes the decoder to run the locomotive at a somewhat constant speed according to the throttle setting. This means that if you set your throttle to 21% of total speed, the decoder will force the motor in the locomotive to maintain a constant speed at that level no matter what the track gradient or the load on the locomotive. The SD9 is an example of a US prototype that employed a load compensating type of control technology. Many modern European locomotive prototypes use some form of load compensation of the prime-mover in response to speed ...

Most modern command stations and decoders are set up to run 28/128 speed steps. If you are using older command stations or decoders you may need to adjust one or the other to get the trains to run.Why are more speed steps better?The reason you want to use a command station and decoders with 128 speed steps is for smoother speed control of your locomotives. Digital command control signals are just that, digital. When you send speed commands with your throttle, you are sending digital instructions telling the decoder to change from the current speed to a different speed. When ...

Problem: PM42 Short Circuit/Auto-Reversing failure when used with Zephyr (DCS50)The PM42 is designed to control 4 independent power subdistricts that can be set up as either a “Short Circuit Manager” (the factory setting) or as an “Auto-Reversing Controller.” The PM42 factory setting for trip current is 3 amps. The trip current can be modified to settings from 1.5 amps – 12 amps to accommodate the needs of your system. In addition, each of the 4 power subdistricts can be set for slow, regular, faster or fastest short circuit management.While a trip current of 3 amps will work with most boosters, ...

In FX3 decoders, CV54 is used to control the decoder's torque compensation and switching speed features. CV53 is not used in FX3 decoders.Torque Compensation improves loco performance by internally adjusting for the loss of torque caused by SuperSonicTM operation. This feature is turned on at the factory.Switching speed gives you fast access to lower speeds used in switching operations. This feature effectively reduces the throttle's target speed by about 50% and reduces the effects of acceleration (CV03) and deceleration (CV04) programmed into the decoder by 1/4 when the user activates this mode by turning on F6.FX3 CV54 Values For Controlling ...

SW01 to SW08 are inputs that allow a local switch mounted on the layout to operate the slow motion turnout machine. For example, SW01 when connected to the +VE sensor common (Pin 2 in figure) will reverse the voltages on SMTM1A and SMTM1B to change the position of turnout 1. SW02 controls local turnout 2 , etc. For each connection to +VE sensor common the slow motion turnout machine swaps direction and a Switch message is sent to LocoNet to report the new position of the turnout. This local control can be disconnected by setting OpSw 15 to closed, in ...

Q: What's a "Bushby bit"? A: In your command station, OpSw27 can be toggled to disable normal switch commands, a.k.a. the "Bushby bit." This allows the layout operator to use an attached PC to handle switch control logic. Under normal conditions, advanced throttles can be used to operate turnouts which are controlled by LocoNet-connected stationary decoders. The factory default setting for OpSw27 is "t". Toggling OpSw27 to "c" takes this control away from the individual throttles and gives it to a controlling computer. Such an application would be a railroad with CTC control, where the train movements are directed by ...

Changing the Direction switch on the top left hand side of the UT4 from Forward (F) to the center Brake (B) position causes the loco to stop at the locomotive’s programmed deceleration rate. Changing quickly from ‘F’ to ‘R’ (Reverse) causes the loco to stop at the programmed deceleration rate, then reverse direction and accelerate at the locomotive’s programmed acceleration rate.

I have a small switching layout, I am interested in low-end speed control and want to control turnouts from the hand held. What components do I need?All Digitrax command staions offer excellent low-end speed control as long as you are using decoders capable of 28/128 speed step operation. Low speed performance will also be affected by how you set up the CVs in the decoder to define how the specific locomotive will respond to system commands. Remember that installing a DCC deocder will not automatically improve the operation of your locos, you will need to first make sure they run ...

What is it and how do I find a DPDT?It's an electrical switch; double pole - double throw (DPDT). Here is a schematic of a DPDT: More typically, they look like this: The DPDT is very common to model railroading and found at just about any store that sells electronics. It comes in a variety of arrangements, with the most common being a DPDT Center-Off switch. Analog OperationsIn the early days of Direct Current model railroading, reverse loops had to be controlled by hand, and the DPDT was perfect for the job. The DPDT was wired in such a way ...

For some reason it is not possible to successfully operate Fulgurex point motors with a DS64. Tortoise work fine. We have determined that the Fulgurex motor draws too much current for the DS64. Published sources describe the Fulgurex motor as needing 400 Ma for operation, which is well beyond the capacity of the DS64. When the DS64 tries to operate Fulgurex motor, the excess current draw appears to be a short circuit and the DS64 shuts down to protect itself. The Tortoise, while also a slow motion point motor, is "on" all the time since it is a stall-type motor. ...

CV29 controls many aspects of the locomotive, including its decoder address (including two or four digit address) , normal direction of travel (NDOT), whether the locomotive opperates at 28 speed steps or 128 and others. Some older Digitrax throttles use hexadecimal notation for programming. This article is presented for the benefit of those who may still be using these throttles. CAUTION: if you are NOT using a DT100 or DT200, please disregard this article to avoid confusion.The Addition Method The table below shows each switch and its value if it is on or off. Notice that if the switch is ...

If you have more than four turnouts, you will need to program the addresses.The DS64 has 4 Output pairs labeled 1R & 1G, 2R & 2G, 3R & 3G, and 4R & 4G. The DS64 is shipped from the factory with these outputs programmed as Switch Addresses 01, 02, 03, and 04 respectively. You can set the Switch Address of each of these four Outputs to any value from 01 - 2048.NOTE: During this procedure the DS64 must be connected to an active LocoNet with an active command station.1. On the DS64’s control panel, press and hold the ID button ...

We recommend testing your new SE8C prior to installation on your layout. The following testing procedures will help familiarize you with the general operation of the SE8C. Track power needs to be ON, a working LocoNet connection and a throttle or PC running DCC control software. Pre-Installation Set-Up 1. Solder one wire from a 12V AC or 15V DC power supply to Pin 3 and the second wire from the power supply to the Pin C on the 44-Pin edge connector; this powers the SE8C. Digitrax manufactures the PS14, which is appropriate for this installation. Multiple SE8Cs can be powered ...

The SE8C uses switch addresses to operate the signals, so you may need to change some factory settings to make it work in conjunction with turnouts that are already installed on your layout. Be sure that when you configure the SE8C that the switch address ranges you select to operate the signals do not conflict with other devices, like DS64s, that are already installed. We strongly recommend that you keep accurate documentation of the address ranges used to control all devices on the layout to avoid conflicts that might cause problems. Without this record it can be very difficult to ...

I'm looking to wire Tortoise switch machines on a DS64. When the track switch is thrown I want to power 1 color light (non-LED). When the track switch is closed, power a different colored light. Is this possible using the DS64 inputs or the Tortoise connections? The DS64 does not have separate connections for indicator lights for trackside or for a control panel. However, indicator lights can still wired to work with the DS64. Tortoise or other slow motion swith machines can be wired in two different ways. If using LEDs, a two leg, bipolar LED can be connected in ...

How To Run a Route with DS64:1. Select the Switch Address that corresponds to the Top Address of the route you want to run.2. Issue a Closed or Thrown command depending on which you set up in the route table.Note that if you are using an actual switch address as your top address and you send the opposite closed or thrown command from that set up in the route; you will operate that switch address only and not the route.For example: If you set up Switch Address 50 as your Top Address by sending a Thrown command, you’ll need to ...

Setting up DS54 for Standard Turnout Reporting The creation of a feedback circuit for standard turnout reporting is simple. Connect a normally open set of contracts attached to the switch machine, a normally open set of contacts of a micro switch monitoring the turnout throw arm, or the normally open contacts of a relay monitoring the switch machine to the common (green) and switch (red) wires to the desired DS54 output circuit. The following two diagrams indicated the two most common switch machine configurations plus the contact configuration for turnout reporting. Note: The location and type of contacts available for ...

The Super Chief can be used to operate routes. A Route is a group of turnouts and their specified positions that will be triggered by the activation of a single "TOP" switch address to a specified position. The DCS100 Super Chief supports up to 32 routes. Each route consists of a list that contains a TOP turnout address and its position (c or t) and up to 7 other turnout addresses and their positions. Routes are stored in the DCS100's memory and can be operated by any throttle in the system that can send switch commands. Each of these 32 ...

I have installed 381-2503 KATO DC turnout machines in the turnouts on my layout and want to move to DCC operation using a Digitrax 245-DS51K1 stationary decoder. Will I have to change my switch machines to #245-DS61K1L DCC machines to do this or stay with the same DC machines? You do not need to change out the turnout motor. The DS51K1 decoder is meant to control Kato UniTrack bi-polar switch machines for both the N-Scale and H0-Scale Unitrack product lines, such as the 381-2503. You can also control these switch machines with the DS64, in groups of up to four. ...

In response to questions about the differences among the DCC systems that are currently available from different companies, I offer the following comments & observations. You may have heard that all the systems are pretty much the same or you may have seen “comparison” charts in various DCC companies’ literature, in magazines or “analysis” on the Internet by “impartial observers.” Unfortunately, it is almost impossible to break down the system and company differences on a simple chart & the people who write the “impartial analysis” are usually not really impartial. As you read these comments, please keep in mind that ...

"Turnout" is a civil engineering term for what railroaders call a "switch". In the model railroad environment, we often use the word turnout to avoid confusion with the electrical term "switch". On the railroad, throwing a switch usually only means one thing, while "Throw the switch" on a model railroad could mean operating a light switch.Probably the best answer is to consistently use one type of turnout. The notion of a "DCC Friendly" turnout is a myth; the standard answer in the past has been: "If it worked on DC it will work on DCC". In the end, which turnout ...

When the BDL168 is connected to LocoNet, it will communicate coded detection information to the system. If you wish to report BDL168 status to LocoNet and attached devices or computers that can interpret these messages, you will probably want to set up a unique board address for each BDL168. This is done so that the BDL168 Board ID does not conflict with the Board ID of other devices on the railroad. Board addresses can range from 01 to 999. It is recommended that you make a record of the addresses you use for all devices connected to your layout. Setting ...

You can use your DT400 series throttle with a DCS100 or DCS200 to set up routes that are triggered by operating a single turnout address to make it either c (closed) or t (thrown). Setting up and operating routes is similar to consisting locomotives because you can cause more than one unit to operate based on a single command sent to the system. We call the turnout address that other turnout addresses are “consisted” to, the TOP address. To operate a route, use Sw (Switch) mode to select the TOP turnout address in the route and move it to either closed or ...

When using an AR1 with the Zephyr Xtra, we suggest you change Option Switch 18 to Closed (OPSw18='c'). Option Switch 18 extends the DCS51 booster short circuit shutdown time from 1/8 to 1/2 second. By increasing this Option Switch setting to 1/2 second, this allows the AR1 to change the track polarity before the DCS51 booster reacts to the momentary short caused when the train passes over the reversing section gaps. To change Option Switch 18, do the following: Press PROG Press SWITCH Press 1 Press 8 Press c (CV-WR, lower right) Press EXIT You will still ...

Can I use the DS64 to power frogs in Atlas turnouts with solenoid ( code 83 ) type switch machines? No, the DS64 does not have internal contacts to provide power to the frogs. This could be done by using a switch machine with its own contacts; these have been made by NJ International, Tenshodo, PFM and others. Another alternative would be to use the Atlas Snap Relay. The Snap Relay is a solenoid device like the switch machine, but instead of throwing the turnout, it throws a set of electrical contacts. The relay is wired in parallel to the switch machine, ...

Q: We will be using your SE8C's for signaling. Should we use the SE8C to control our slow motion switch machines, or should we use your DS64s for that function? A: Both products will do the job. How you plan to use them on your layout will help you decide which is better in your situation. Here are some things to consider in making your decision:The SE8C will drive 8 slow-motion switch machines while the DS64 will drive four. If you have a large number of switch machines in a specific area, the SE8C might be a better choice, since the ...

The DCS50 Zephyr normally treats Function 3 as an on/off function unless you set it up as a non-latching function like Function 2. This means that F3 can be used either as a normal function operating as an "On / Off" switch, or to control a function that only requires a momentary activation like some couplers.To set up Function 3 as a non-latching function, set the DCS50’s Option Switch 6 to closed as follows:1. Press the PROG key. The last programming mode used by the DCS50 will be displayed.2. Press the SWITCH key. The display shows the last switch used ...

CV54: Torque Compensation & Switching Speed In FX3 decoders, CV54 is used to control the decoder's torque compensation and switching speed features. Torque Compensation improves loco performance by internally adjusting for the loss of torque caused by SuperSonic™ operation. This feature is turned on at the factory. Switching speed gives you fast access to lower speeds used in switching operations. This feature effectively reduces the throttle's target speed by about 50% and reduces the effects of acceleration (CV03) and deceleration (CV04) programmed into the decoder by 1/4 when the user activates this mode by turning on F6.

The green CONFIG Indicator shows the primary operating mode of the DCS100. This indicator should be steady green blinking off briefly once every 4 seconds. This indicates that the setting for DCS100 Option Switch 05 is set up correctly. If you see 8 blinks every 4 seconds then we recommend that you change the DCS100 Option Switch 05 to closed. The DCS100 will operate correctly in either case. The CONFIG Indicator will be mainly off when DCS100 option switch 01 is incorrectly set to closed. In this case you must change option switch 01 to thrown for correct operation.

Can the output of the DS44 power more than one Tortoise switch machine at the same time? No, the DS44 was designed to only drive one Totoise switch machine on each of its four outputs. Connecting more than one Tortoise switch machine is not advised and could burn out the DS44.

When DCC locos enter a brake section with braking on, they will receive braking commands from the command station instead of normal DCC operating commands. DCC locos in this braking section will come to a stop. When you throw the switch to allow normal DCC commands, the DCC locos will resume normal operation. Once the DCC loco has left the brake section under normal DCC power, simply return the switch to the break position so that the next DCC loco will stop in the section. This is useful if you want to have trains stop at stations around the layout ...

I am trying to wire my new layout (N gauge) using the DS 64 with Peco switch machine PL10. The PL10 has four wires to be attached. My question is: Do I need to attach all four wires or just one set of wires? The PL-10 is a coil-type switch machine with double solenoids. One solenoid is activated to make the track switch throw in one direction, and the other is activated to throw it in the other direction. All four connections are required, with one for each solenoid being common and the other two being for the individual coils. ...

One special feature on the Texas & Southwestern is a built-in programming track. The programming track is located in a short section of track in the small engine terminal of the T&SW. This track has both rails insulated from the rest of the railroad. It uses a Double Pole Double Throw (DPDT) toggle switch to select what purpose this section of track is used for. When the toggle switch is set in one direction, the track has DCC power on it. When the toggle switch is aligned in the other direction, the track is now connected to the programming terminals ...

The DCS50 Zephyr displays three types of error messages: Short circuit shutdown occurs when the DCS50 detects a short circuit in the power district where it is connected to the layout. This can be a loco that has derailed or picked a switch or some other conductive material lying across the tracks. In this case you will see “o”s walking across the display from left to right. Once the short is cleared, the DCS50 will resume normal operations. Current overload occurs when the DCS50 has reached its 2.5 Amp current limit. In this case you should run fewer locomotives or ...

The DS64 is a powerful stationary decoder. If you have tried to program this stationary decoder and are having problems, there are several things that you can do before contacting Tech Support for further help. Is the DS64 receiving enough power? The DS64 can be powered in several different ways. Although it is possible to power the DS64 from track power, this has been a source of problems for many operators due to low voltage. This typically arises on a railroad that is using power in excess of the capacities of its power supplies. Have you programmed all four addresses ...

How do I set up the SE8C to control semaphores? Installing Semaphore Type Signals with SE8CThe SE8C can be set up to use its 8 turnout motor drive outputs to run 8 three-position semaphore (arm type) signals using slow motion turnout control machines (such as the TortoiseTM machines) as actuators. These 8 semaphore signals are available in addition to the standard 32 LED signal heads on the 8 signal control cables and occupy a separate semaphore address control range.The SE8C automatically sequences the three possible mechanical arm positions to match 3 aspects of red, green and yellow using a position ...

When using more than one DS64 in a DCC environment, you must assign a Board ID to each additional DS64 so that each one has a unique Board ID.You will need to set the DS64's board ID if you are planning to use the DS64's 8 inputs with a computer, system throttle, or other smart device on your layout that needs to know when a turnout has been manually thrown or closed via a particular DS64.You can use the 8 inputs on the DS64 to control the operation of the 4 outputs that control your turnouts. For example, you can ...

Q: I am the only operator. There will be no others. I wish to use block detection for signaling. However, I find that I cannot use the BD4s in the way I thought they could be used. My question, must I divide my simple layout into blocks (which DCC says you don't really need) in order to use the BD4's and SE8C together? A small basic layout can be operated in the DCC environment without dividing the railroad up into power districts. In this scenario, you will use one command station/booster to power the entire layout. As your power consumption ...

When using a DCS100 or DCS200 to setup routes within the Command Station in conjunction with DS64 Stationary Decoders, the DS64 needs to be connected to Track Power. The DCS100/200 does not send internal route messages via LocoNet. DCS100/200s only send Routes as a series of switch commands out to the Track in DCC format. The DSC100/200 were designed in 1996 and had no requirement to echo these same switch commands out via LocoNet. Additionally, DS64 Stationary Decoders are designed to allow up to 8 Routes to be programmed internally into them. Please refer to the DS64 manual and other ...

The DCS50’s LED Display is made up of 4 digits/letters on the main part of the screen and 4 Indicator Dots across the top of the screen. When you are running a locomotive, you will see the address of that locomotive in the display and the Function Indicator Dot will be lit. This means that the throttle knob will control speed, the direction lever will control direction and braking and the number keys will control the functions on the locomotive. You will see the following display if you are running loco address 1873 on your local throttle.The LCD has three ...

There is a numeric keypad on the DT402/DT400 throttle. The numeric keys on the keypad are primarily related to the throttle mode shown in the LCD’s mode indicator area, but can be used for numeric entry and function control in other modes. For example, when the command station is in the Function Mode Fn, the numeric keys are used for function control. When the command station is in the Locomotive Mode,Lo, the numeric keys are used to enter loco addresses. When the command station is in the Switch Mode is Sw, the numeric keys are used to enter switch addresses.In ...

I want to run a small 12V -16V AC motor via DCC and am not sure if you have a decoder for this and if so how to connect up.For Variable Speed:Some Digitrax decoders, such as the DG583S, can be programmed to operate AC motors. When you program CV61 to a value of 004, Digitrax decoders with split field motor drive capabilities will convert their motor leads to drive a "split field" AC motor instead of the default DC motor. This lets you run Maerklin 3-pole AC motors and similar motors in a number of locos built in Europe with ...

If a Zephyr has been switched to run as a booster/throttle (no command function), can it still be used to program locomotives on the programming track? No, when using the DCS50 as a booster, the programming outputs are disabled. Programming is a function of the command station only, so when the Zephyr is toggled to booster mode, it loses the programming function. If a Zephyr has been switched to run as a booster, does the throttle still work? Yes, but you must assign an unique throttle ID to the Zephyr which is acting as a booster. Assigning Throttle Identities To ...

The actual track voltage supplied by the DB150 can be adjusted. To do this, you must open the DB150 case (this will not void your warranty). 1. Open the DB150 case. Remove the black screws on the top and bottom of the case and slide the gray front panel off. Be careful to avoid disturbing components other than the ones described below. 2. Locate the small yellow trimmer potentiometer behind the LocoNet B Jack and Scale Switch. 3. Use a small screwdriver to turn the potentiometer clockwise to increase the scale voltage setting. Turn it counter clockwise to decrease the ...

Track voltage on DC (analog) layouts can be measured from rail to rail. However, with DCC layouts that use direct home wiring as recommended by Digitrax, this method of measurement does not work with most voltmeters.Track voltage (output from the booster to the rail) on DCC layouts with direct home wiring can be measured as follows:1. With the system powered up and with the TRACK STATUS LED on, use your throttle to select the analog address 00 and set the speed to 00.2. With a multimeter set to the 20 volt DC scale, measure the voltage from RAIL A ...

What happens when I select a loco that is currently running at a different speed than the throttle is set to? example... running loco 'a' at half speed then switch to loco 'b' does loco 'b' suddenly change speed to half throttle? (which is the last position the knob was indicating for loco 'a' this would make for a nice crash if I planned on backing loco 'b' out of a siding, and it goes forward instead at 50% right into a bumper) You're right, when switching the loco 'b', the newly selected locomotive would be commanded to operate at ...

Zephyr Xtra (DCS51) and Zephyr (DCS50) systems can program Soundtraxx Tsunami decoders using Blast Mode Programming on the Mainline. Blast Mode Programming will program EVERYTHING sitting on the main line track so, you MUST remove everything from the track that you are not programming or use an isolated piece of track connected to Rail A & B. NOTE: Track power must be ON during Blast Mode Programming. You will not be able to read back CVs using Blast Mode Programming. To use Blast Mode Programming with Zephyr, close Option Switch 7. 1. Press the "PROG" key. 2. Press the "SWCH" ...

If Zephyr DCS50/DCS51’s display shows FuLL this means that it has reached the limit of 10 (20 for the Zephyr Xtra) locomotive addresses that it can manage at one time. If you want to select additional addresses, you will need to release one or more loco addresses before you will be able to select other locomotives to run.The DCS50/DCS51 runs a “purging” routine that helps eliminate addresses that have not been used for a period of time to make slots available for running other addresses.If you see this "FuLL" message while you are operating, you can release locos that you ...

Q: How do I use the AR1 and automatically control the turnout? I'm confused here. It is good that the AR1 controls the switching of the track power for a reverse loop automatically but it seems the turn out direction also needs auto control. Am I missing something here? Need help understanding...Please explain. A: The AR1 is handles correcting the track polarity mismatch when a reversing section is encountered by a locomotive. When the polarity inside the reverse section does not match the polarity outside the reverse section, the AR1 detects the short circuit and flips the polarity so that ...

Problems occurring on most auto reversing sections are a result of improper wiring or gapping. Digitrax auto reversing units such as the PM42 or AR1 require a "hard" short which means there must be good current flow to both sides of the gaps, on the reversing section side and on the "normal" side. Our experience has been that over 90% of reversing section problems are a result of improper wiring or improper gaps. Another 5% is a result of improperly wired or configured auto reversing units. It is poor practice to put the gaps immediately behind a switch (turnout in ...

Q: I have an MRC RailPower 1370 DC power pack. I was wondering if that would work as a jump throttle on my Zephyr till I get my UT4 LocoNet Throttle? A: We think that the answer is "No", but you will need to verify whether this power pack produces pure or pulsed DC power directly with MRC. Throttles used with Zephyr Xtra via the Jump Port must produce pure DC power, often referred to as "smooth" power packs. Many "advanced" analog power packs use automatic pulse injection to make model locomotives run better at slow speeds. This uses 1/2 wave AC ...

Shutting Down the System When you are finished with your sessionDispatching All Locomotive Addresses Some users prefer to “dispatch” or release all addresses active in their system before shutting down. This can prevent unexpected results when you power up the layout again. 1. Turn track power off: Press the PWR Key followed by the N - Key , the Track Power Indicator on the DT400 and the Track Status Indicator on your command station will go off. 2. Move the DB150 command station’s “MODE” switch to the “SLEEP” position. 3. Turn off the power supply to the system. Leaving the ...

There are three different ways to power the DS64. Track power (Trk A and Trk B), Auxiliary power (AX1(-) and AX2(+)) and power through the rear modular power connector. Connect the Trk A and Trk B screw terminals of the Power and Track Connections to the corresponding Rail A and Rail B track connections. The PS14 power supply can be used with Auxiliary or the rear modular power connector. The DS64 requires 300mA for proper operation. Only one DS64 can be powered per PS14. A generic DC power supply between 12-16vdc and 300mA can be connected to a DS64 ...

Resetting Factory Defaults You are unlikely to encounter a problem that will require a factory reset. One such instance may occur if you set a password for your Duplex Group name and forget what it is. Resetting to factory default condition is an easy way to correct the situation. Note: If you have more than one UR92 in your layout, you will want to disconnect all of them to do a full factory reset on each unit as follows. Once they have been reset, reconnected to your LocoNet, and allowed to renegotiate a common Group name; you can change the ...

The DT402 & DT402's screens are an LCD (Liquid Crystal Display) that is designed to show you what you are controlling with the throttle. It also facilitates programming and other features of the LocoNet system. 1. The handheld has two throttles called the left throttle (L) and the right throttle (R).2. There are two direction indicators. One for the L throttle and one for the R Throttle. If the direction indicator is lit, and there is smoke over the loco icon there is an address selected on that throttle.3. The direction indicator with blinking smoke indicates which throttle is currently active. The ...

A cascaded route is where the last command of a route triggers the next route; this is also known to some as a nesting route. With the capacity of 8 turnouts per route, it becomes necessary to cascade routes if more than 8 turnouts are involved in a route. To highlight these possibilities, we use a very complex scenario with many turnouts and possible routes. Cascading routes allows the setup of long routes without the need for a computer. Since some routes exceed the capacity of 8 turnouts, the remaining turnouts of the long routes are setup in the second ...

Setting up your new Zephyr: Unpack the DCS-50 command station and the PS-315 power supply. On the back of the DCS-50,locate the gray screw terminal strip.On this strip, locate the two terminals labeled “RAIL A “and “RAIL B”.Attach these terminals to your track wires.It does not matter which is which. Before proceeding to the next step,make sure the throttle knob [1] is turned all the way to “stop” and the direction/brake lever [2] is set to”brake”. [See photo blelow]. Now, find the plug on the back of the DCS-50 marked “POWER IN, 15 VAC, 2.5 AMPS”. This is where you ...

How Many UR90 Infrared receivers will I need?One UR90 should provide complete coverage if your room is typical, with a hard surface floor and finished walls and ceiling. However, several things can cause the need for additional UR90s, such as: larger room, odd shaped room, acoustical ceiling, carpeted floors, or book shelves or other things on the walls that can interfere with the infrared signal. How many more you'll need depends on how many of these "impediments" are in your layout room. This Infrared signal should be considered to be line-of-sight, but the IR signal does reflect off of other objects, thus the concern ...

Decoders with FX3 features have 8 user configurable, independent special effects generators. All current production Digitrax Decoders use FX3 function features. These are set up by programming CV values as described below. If your decoder is not a Series 3 decoder, please check the spec sheet to determine which type of functions it supports.FX3 functions incorporate FX generators with additional dynamic and static qualifiers. FX3 functions are fully remappable so they can be controlled by any function key on your system. A master light switch can be set up to turn off all lights on a locomotive. Functions associated with advanced ...

I don't understand what the white cam lead gets hooked up to. Some model steam locomotives are equipped with, or can be equipped with, a cam arrangement which coordinates the sound to the rotation of the drivers creating chuffing. As the wheels turn, a switch opens and closes, operating the chuff sound produced by the sound decoder. The white wire goes from the decoder to a microswitch which is operated by a cam that is mounted on the axle of one of the drivers. In operation, when the white wire senses the DCC track signal, it operates the chuff sound ...

Some DCC systems need to have CV's 17 and 18 programmed separately to assign the decoder a 4 digit address.Digitrax command stations handle this automatically by default. If you have a decoder that needs manual entry of CV17 & CV18, follow these steps:You cannot simply split the four digit address in 2 halves and input these into CVs 17 and 18. A conversion from decimal numbers to hexadecimal numbers is required. Once the hexadecimal conversion for the 4 digit address is performed, this number is then split in half and then each half is input into CV17 and CV18 respectively.To ...

Simplex Radio Coverage One UR91 should provide full coverage for a typical model railroad under most circumstances. Simplex Radio reception is affected by metal objects between the throttle and UR91 simplex receiver, or large metal objects adjacent to the receiver; a furnace is one example of such an object. Such objects cause a second reflected signal, impairing the radio throttle signal's ability to reach the UR91. In this case, the receiver gets the signal directly from the throttle, then another signal right on top of it from the reflection. Moving the UR91 to another location may solve this problem, or you ...

The DCS100, 200, 240 and DB150 use several beeps and clicks that can be used as diagnostic tools that will help you debug a number of error conditions. DCS100/200 Audible Sounds 1 Beep DCS100/200 has powered on successfully or has sent a programming command. 3 Beeps A loco address has been "purged" due to non-use. This is informational only and is normal. 4 Beeps Booster short circuit shutdown. Fault Alarm. 6 Beeps Command station already present in system.

The Kelana Jaya Rail Line model is a DCC intense layout, using many Digitrax command control components to achieve the goal of training operators of the actual rail line. The railroad was built in the 1990's and many of the Digitrax devices used for the Kelana Jaya Rail Line model have been superseded with improved units. Components used for the Kelana Jaya layout: 28 Mainline turnouts 11 Yard turnouts 39 Tortoise switch machines 84 Dwarf signals (yellow/green, red/green, red/yellow) 38 Mainline block signals 38 Heavy duty SPDT switch relays Digitrax Components Used for the Kelana Jaya layout: 1 DCS 100 ...

These instructions will get you up and running quickly. A full description of all controls and technical reference information are included later in this section of the Tech Support Depot. This section assumes that you are using a new set straight out of the box. If your set is radio equipped, we recommend that you follow this quick start guide without using radio to learn the basics. When you are successfully running your radio throttle tethered to the system, then go to the DT400 series tetherless overview article to learn how to install the radio option. Connect the DB150 to the ...

The mode indicator, located at the bottom center of the LCD, shows the DT300’s current mode of operations. The DT300 automatically defaults to the Lo (Loco) mode and returns to this mode after about 6 seconds of inactivity in Mu (Multi Unit) or Sw (Switch) modes.

Q: Can I use non-Digitrax decoders on a Transponding layout?A: Yes. If you want to add transponding to a decoder that does not have the feature, add TL1 or TF4 to the decoder. Some non-Digitrax decoders that use supersonic features are not compatible with transponding unless you switch off the supersonic feature. Digitrax supersonic decoders are compatible with transponding and can be used in supersonic mode while transponding.

You can add a second Zephyr to add more power and an additional throttle on the DCS50 and two additional Jump ports for using DC power packs to control DCC locomotives. You will need to change Option Switch 02 to c (Closed) on the second (and any additional DCS50s you might choose to add to the layout as well). The diagram below shows you how to do this.

I am not sure what example railroad he is talking about. ZHere is a control panel display example for our example railroad using Railroad & Co.: This is the way that an actual railroad dispatcher would control our example railroad. Although the three sidings are not controlled by the dispatcher, they are still shown because the positions of their points have a material affect upon train operations. A train approaching an open turnout would be put at risk, so the position of these turnouts is considered to be part of the control system. These sidings would be manually controlled by ...

How to Configure the DS54 for one-button turnout controlThe local buttons, throttle, or any other turnout control device connected to the LocoNet can control the DS54 output when the DS54 is connected to the rails. The following drawings indicate the general wiring schematic for a one-button control of a turnout using either a Dual Coil (upper) or slow motion (lower) switch machine. The following two charts indicate operating criteria and CV settings for one-button turnout control.

Q: What is a programming track? A: A programming track is a section of track that is used to program the mobile decoders in locomotives. Sometimes it is called the service mode track or service mode programming track. It must be electrically isolated from the rest of your layout and connected to the Prog A and Prog B terminals of your command station. The programming track can be completely separate from the rest of the layout or can be isolated by double gapping and using an electrical switch to allow locos to move from the programming track to the mainline before and after programming. Usually ...

Q: Since the back emf torque compensation feature make consisting a real headache, I would like to know how to switch that feature off. Prototype loco's don't have such a thing so that slowing on a grade isn't really a bad thing in a model, either. A: You can turn turn the speed stabilization on or off with CV57. The CV value range for CV57 is 0-15. If CV57 = 0, speed stabilization is OFF. If CV57 = 15, speed stabilization is fully on. All values in between let you scale how much speed stabilization you will use with each ...

Hook up for slow motion type turnout machines & crossing gates.Note: Multiple turnout machines of the same type can be operated on a single DS64 output.For example, you can run 2 Tortoise or Switchmaster machines on a single DS64 output.Note: If you find that your turnout is operating “backwards” simply switch the + & - wire connections to achieve correct operation.Note: The outputs can be configured to drive a grade crossing signal. See Knowledge Base article.

The MODE key is used to move from one operational mode to another on the DT300 throttle and to dispatch selected addresses or consists to make them available for use by other throttles in the system. Lo (Loco) mode is the DT300’s default mode since most of the time you are running locomotives.Press the MODE key to cycle from Lo (Loco) mode to Sw (Switch) mode to Mu (Multi Unit) mode and back to Lo, and so on.The current operation mode will show in the middle of the bottom row of the LCD display.Dispatch: To Dispatch or offer a locomotive ...

The OPTN t Key is used to enter the Option Mode to set throttle and system options. It is also used to issue t (thrown) commands when the throttle is in Switch mode.In the case of turnout control:t=thrown, when a "t" command is sent, the turnout is set for the diverging route through the curved leg.

The UT4 series, UT4, UT4D & UT4R are "traditional" style throttles. The UT4s were developed from a specification submitted by Digitras users through the Digitrax Yahoo group. These throttles were designed by operators for operators. They are also great for beginners because of their intuitive controls and reduced feature set. By not offering all the bells and whistles, beginners can run your railroad without accidentally changing settings that might cause problems. Works with any LocoNet compatible system 4-Digit addressing Functions F0 - F12 for lighting and sound decoder operation Direction switch with center brake position ...

Selecting a locomotive-Safety Selection While unplugged, the DT402 (IR only) and DT402R (IR and Simplex Radio) operate as one-way transmitters. The DT402 and DT402R must be plugged into LocoNet to select an available locomotive address. After an address is selected, you can unplug from LocoNet and run the selected addresses with infrared or simplex radio. The throttle will automatically convert to infrared or simplex radio operation for all speed, direction, function, operations mode programming, and switch commands. The DT402D throttle has full duplex radio capabilities. Once the 402D has been configured to communicate with a UR92, the full functionality of ...

CV29 is assigned a single value which chooses a combination of specific effects: 1. Speed step control. 2. Speed table On or Off. 3. Analog mode conversion On or Off. 4. Normal Direction of Travel (NDOT). 5. 2 digit addressing or 4 digit addressing. Speed Tables: Speed tables can be enabled or disabled with CV29. Speed tables are used to customize the throttle response curve of each decoder equipped locomotive. The speed table values can be stored in the decoder and then the table can be turned on or off with CV29. One example of such usage would be ...

The CLOC, "c" Key is used to toggle between displaying and not displaying the current fast clock time. It is also used to issue c (closed) commands when the throttle is in Switch mode.In the case of turnout control:c=closed, when a "c" command is sent, the turnout is set for the main line with routing through the straight leg of the turnout.

I have multiple reversing districts, do I have to buy a separate booster for each one?You can run more than one reversing district off a single booster, but there is the potential problem that might arise is if you have more than one set of wheels crossing more than one set of gaps at the same time. In this case, the booster will detect a short and shut down (unless the polarities just happen to be matched up in which case you won't see a problem). We recommend that you use the AR1 Auto-Reversing unit or the auto-reversing capability of the ...

When you program the DS64, you must program all four outputs, even if they are not connected to anything. A "Virtual" top address can be used to avoid conflicts with actual turnout addresses and other routes. To create a virtual top address use a switch address for your top address that is not used to operate an actual turnout on the layout. The advantage of this is that you can consistently use either the "thrown" or “closed” command to operate all routes, making it easier to remember which position goes with which route to make them work. Since DS64 routes ...

Overview:To reset locomotive electronics to factory defaults the user must set CV08 to a value of 08. It is recommended that this procedure be performed on the dedicated service mode programming track using direct mode programming.* Note: This is the only programming procedure that we recommend using the programming track for. All other programming should be performed on the main track using Operations mode programming.Procedure:1. Place the DCC equipped locomotive on a dedicated service-mode programming track.* Note: The rails of this track should be connected to the PROG A & PROG B outputs on the DCS100 command station.2. Set the ...

I have an old Diamond Scale turntable; this turntable uses a rotary switch to select which stall or track you want to align the table with. It is basically a closed connection, or relay connection to select the track you want. I was wondering if it was possible to use the DS64 to create a closed connection (relay output) to activate this connection for the turntable position. Basically I want a relay output from the DS64 to be addressed by my DT400. Using throttle control This should be fairly easy, but not in the way that you envision it. The ...

The actual track voltage supplied by the DB200 can be adjusted. To adjust the track voltage, you must open the DB200 case (this will not void your warranty). 1. Remove the DB200 input power & disconnect all DB200 leads. 2. Remove the two screws on the top and bottom of each side of the case. 3. Slide the gray front panel off the DB200. 4. Be careful to avoid disturbing components other than the ones described below. 5. Locate the small yellow trimmer potentiometer behind the LocoNet B Jack and Scale Switch. 6.

I was wondering if I could use an output on the DS64 to momentarily apply power to a Kadee #309 electric uncoupler? OpSw 02, 03, 04, &05 closed would give me a 3 second pulse. The Kadee uncoupler may require as much as 3 Amps @ 22 Volts. So, what is the current carrying capacity of the outputs on the DX64 [sic] ? What is the maximum DC voltage I can apply to terminals AX1 and AX2? The DS64 can accept 12-16 volts AC or DC on the rear modular jack or 12-16 volts DC on the AX1 (-) / ...

Some users prefer to “dispatch” or release all addresses active in their system before shutting down. This can prevent unexpected results when you power up the layout again. 1. Turn track power off: Press the PWR Key followed by the N - Key , the Track Power Indicator on the DT400 and the Track Status Indicator on your command station will go off. 2. Move the command station’s “MODE” switch to the “SLEEP” position. 3. Turn off the power supply to the system. The power to the command station can be left on all the time if desired. In “sleep” ...

Kato makes a Unitrack double-crossover, their No. 20210: Kato has advised us that this unit has four solenoids in its base, each operating one turnout point set. Connecting the DS51K1 to the red / black wire pair at the base of the track will damage the decoder since the four solenoids of the crossover will draw more than the rated current capacity of the DS51K1. If you are wiring the DS51K1 internally to this track segment, it is easiest to program each turnout pair to the same address; done this way, activating one track switch address will result in the ...

While tetherless, the DT400/R operates as a one-way transmitter. The DT400/R must be plugged into LocoNet to select an available locomotive address. After an address is selected on your DT400/R, you can unplug from LocoNet and run the selected addresses with infrared or radio. The throttle will automatically convert to infrared or radio operation for all speed, direction, function, operations mode programming, and switch commands. Digitrax uses this safety selection procedure, which requires throttles be plugged into LocoNet to select a loco address to run. This is an important operational safety feature. Digitrax chose not to allow one way address ...

Many Digitrax SoundFX decoders come with two different sound schemes pre-installed. Check the decoder instruction sheet for which sound schemes are installed in the decoder you are using. Instruction sheets are available on this website on the product pages for each decoder.The decoders come from the factory with CV60 programmed to a value of 01 to play the default scheme. If you want to play the other pre-installed sound scheme, simply program CV60 to a value of 00. You can switch back and forth between the two schemes. Changing CV60 does not erase either pre-installed schemes.If you want to download ...

This Application note shows how Marklin Users can have the power and reliability of Digitrax boosters along with their Marklin command stations! Notes: 1. Before applying power to the booster, use a short length of wire to short the 2 gray terminals (SYNC & GROUND) on the DB100. This forces the DB100 into the booster mode when the power is applied to it. Set the MODE switch to "P/R" for auto reversing operation or to "RUN" for normal booster operation. 2. Make a cable with 6 conductor RJ12 cable with a 6 conductor male plug on the DB100 end and ...

Each DCC decoder that is installed in a locomotive is assigned a unique address. To select a locomotive and run it on either throttle, you must know the address assigned to the decoder. Digitrax decoders are set up at the factory with the “default” digital address of 03. This means that when you take a Digitrax decoder out of the package and install it in your loco, you can select address 03 on your throttle and run the decoder. The first Configuration Variable (CV) programmed by most DCC users is the decoder’s address since it is not very useful to ...

This example is a small yard with a crossing signal at its entrance. We will use independent turnout addresses to demonstrate the flexibility that the DS64 offers. Here, route (track) 2 3 and 4 will activate the blinking light when set and the deactivation is done by resetting to route 1, the main line. The advantage of this setup is that you can easily do operating RR Crossing lights without the need for additional equipment for block detection. The turnout output utilized for the RR crossing operation is simply integrated into the route setup. In addition to the route ...

Digitrax Command Stations can operate one locomotive on your layout that does not have a decoder installed. This loco is called an "analog," "conventional," or "non-DCC equipped" locomotive. To operate an analog locomotive with Digitrax you will use address 00 to send commands to the locomotive. The magic that makes this happen is called zero stretching. With Zero Stretching, an analog locomotive going forward receives an unusually long positive voltage, followed by a very short negative voltage. The much larger positive voltage ensures the locomotive moves forward. The brief negative pulse causes a low buzzing that will vary with the speed of the locomotive. This method ...

Scaleable speed stabilization (back EMF) compensates for load by providing more voltage to the motor. If there is a mechanical problem with the locomotive that greatly increases this load you can prevent damage to motor by setting CV57 to limit how much throttle can be added due to BEMF.Digitrax Scalable BEMF uses CV57 to control how much compensation authority the BEMF control loop has. The higher CV57 is (0-15 range) the more back-emf the control loop can crank in; a value of 0 effectively turns off BEMF compensation. The value in CV57 takes into account the different throttle levels as ...

Q: What is the basic configuration and Option Switch (OpSw) settings for each of the four sections of the PM42 when configured for automatic reverse section control? A: The PM42 is a 4 section multi-purpose device where each of the four sections can be individually configured to act as either a circuit breaker, or auto-reverse section controller or DPDT relay. When configured as an auto-reverse section controller, the PM42 adjusts the rail phasing of the reversing section it controls whenever a locomotive, or car with metal wheels, bridges the gaps between the rails of that reverse section and an adjacent non-reversing section ...

The two "POWER IN" terminals on all Digitrax boosters & command stations are the power input connections. Digitrax recommends the PS514 to power the DC200 and DB150. Set the voltage setting on the PS514 to 16.8v or 19v. The PS2012 can also be used to power the DCS100 and DB150. The "Y" cable provided with the PS2012 has an embedded 5 amp current protection. The PS2012 can also be used to power the DCS200. The "Y" cable is not suitable for use with the DCS200 since it has an 8 amp. output. When powering your layout, make sure that all polarities and ...

This document outlines the power requirements for Digitrax LocoNet accessories. To simplify wiring, Digitrax recommends providing individual power supplies for like accessories. For example a power supply or power buss which only powers the PM42s. A power supply or power buss used solely to power multiple DS64s. UR9x and UP5 panels can be daisy chained provided adequate current is provided to properly power all the panels. Through the use of individual power supplies, the chance of Ground Loops or sneak paths back to ground is minimized. Using individual power supplies will also make troubleshooting much easier. Many Digitrax LocoNet ...

Q: I am building a new DCC layout that will include a logging spur that is simply a single long piece of track with no loop. I want to have a train go back and forth on this track which automatically reverses when it gets to each end. While the AR1 was designed for reversing loops, can it be wired to simply reverse a train on a straight piece of track? A: Not in the way that you intend. One of the interesting problems with DCC is that we often still think in terms of DC, where the track polarity ...

You can operate reversing sections manually or automatically with Digitrax. You must double gap (completely isolate) both ends of the reversing section just like with any other layout. If you choose manual operation, use a DPDT switch or relay to handle the polarity change as the loco enters and leaves the reversing section. If you choose to use to completely automate the reversing section, power the reverse loop with a booster and power supply and the main layout with another Command Station and power supply. The WTL12 when running as your command station will not auto-reverse. To configure your ...

Q: How can the DS54 be configured to control a Flashing Crossing Signal? A: The elements necessary to create a simple function flashing/blinking crossing signal are: a block occupancy detection (trigger) device, an electronic flashing/blinking circuit (DS54) and a crossing signal. The DS54 can accommodate two different types of triggering devices: Digitrax block occupancy devices (BD1 and BD4) and third party block occupancy devices (such as magnets and reed contacts). The following drawings indicate how to connect the two different types of triggering devices, along with the crossing signal, to the DS54. The upper drawing is for the BD1 or ...

Digitrax's “safety selection” is an important operational safety feature. Digitrax chose not to allow one way address selection to prevent multiple operators from being able to select and send commands to the same addresses at the same time. Having multiple operators sending commands to the same address can result in serious problems in an operating session because locos can appear to be out of control. Simplex radio throttles like the DT402/R, DT400/R, DT300/R, UT4/R and similar throttles operate as one-way (simplex) infrared or radio transmitters. The DT402, DT400/R, DT300/R, UT4/R must be plugged into LocoNet to select an available locomotive address to run on ...

This Atlas Snap-Track layout appears in the Atlas Model Railroad Company's book "Beginner's Guide to HO Model Railroading". It includes a reversing section which can be controlled with a Digitrax AR1. DC Control For DC operation, Atlas specified an Atlas Controller (for the reverse loop), two Atlas Selectors (to control eight track segments) and seven controllers for the railroad's turnouts. DCC Makes Things Simple With DCC, the wiring of this railroad is considerably simpler. Because each locomotive has a unique address, the section insulated gaps and the two Selectors are not necessary. Likewise, the Controller is replaced with the AR1 ...

When I hook up my USB cable to my PC the DCS240’s blue USB led turns on, but Digitrax DigiIPL II, LocoMon and SoundLoader II utilities do nothing when opened. What is the problem? The blue USB led lit on the DCS240 means that the complex USB Enumeration and startup sequence has successfully completed. Be sure to select the correct COM port number that is now associated with this DCS240 in the software you are trying to use. You can see this COM number appear in the “Ports (COM & LPT)” entries of e.g. the Device Manager function of Windows, ...

In this orientation, Pin 1 (the orange wire) is the lower left pin and Pin ...

When you hear 7 beeps when power is applied to your DCS100, you need to replace the CMOS battery. The DCS100 will continue to operate, even if this battery is not present, but all your memory settings and option switch settings will not be remembered when the DCS100 is powered down. To replace the CMOS battery without losing any memory settings: 1. Remove the DCS100 input power & disconnect all DCS100 leads. 2. Open the DCS100 case: a. Remove the two screws on the top and bottom of each side of the case. b. Slide the gray front panel off ...

You can have the power and reliability of Digitrax boosters even if you use a Lenz Command Station. You can use Digitrax boosters to automate reverse loops, too. Digitrax boosters can be used with the Lenz Command Station to provide more power for driving the layout. Many customers are using DB150, DB200, or DB100 series boosters instead of LV100's because the DB150’s & DB100's are very reliable 5 amp boosters with plenty of heat sinking capability to prevent heat related booster shutdows. Equipment needed: 1) A Lenz LZ100 Command Station. 2) A DB150, DB100 or a DB200 series booster. 3) ...

Q: I recently split my layout in half, with a DB150 acting as a booster powering one side and a DCS100 powering the other. I'm trying to reconnect the bus feeders to the rails, which all worked properly before the split. Now when I reconnect the feeders there is no short indication, BUT when a loco goes over the insulated gap between the two sections, a short occurs. A: This is a common issue when the first booster is added to a DCS100/DCS200 command station. MOST DCS100/DCS200 command stations come from the factory set with Rail A & Rail B connections that are the opposite ...

CV133 and CV134 work together to control chuff timing. CV133 and CV134 can be adjusted to create the desired chuff rate in your locomotive, or you can configure your sound decoder with CV133 and CV134 to use an external cam to create chuffing sounds. CV133 Steam Chuff/CAM configurations: CV 133 set to a value between 1-127 determines the driver size in inches. (Default Value = 63) CV134 Steam gear ratio trim CV 134 set to a value of 32=100% ratio. Setting CV133's value from 1-127, puts the sound decoder into 'Autochuff' mode. Autochuff mode tells the decoder to simulate driver ...

If you are NOT plugged into a LocoNet port1. Use the 4 rotary address selector knobs on your UT4 to dial up the 2 or 4 digit address of the locomotive you want to run. To enter a 2-digit addresses, set the first two selector knobs to 0 and enter the two digit address on the 2 address selector knobs on the right hand side of the throttle (for example 0025).2. Plug the UT4 into any LocoNet port and automatic selection occurs.3. A Green Status light confirms that selection has been done successfully - You’re off and running!4. A Red Status light means the loco is ...

The layout uses twenty-eight turnouts on the mainline and an additional eleven turnouts in the yard. Each turnout is powered by a Tortoise slow motion turnout motor. Each of the twenty-eight mainline turnouts has three dwarf signals associated with it. The aspects of the signals are shown below. The indications of the signals are: Green = Proceed Yellow = Proceed with caution Red = Stop Each signal has one head with two LEDs. There are also thirty-eight mainline block signals (red/green) that are controlled by heavy duty single pole double throw relays. This makes a total of 122 signals. Since ...

Background The world is filled with places like Nemo Junction, a crossing between two railroads which is protected by a signal interlocking plant that also serves as an interchange point between these railroads. Cars destined for places to and from another railroad are exchanged at places like these. The interchange has been described as being the ideal model railroad industry because any type of car can be found there, heading toward places that are not on the model railroad itself. Nemo Junction is based upon a real place, a location in Illinois identified on the timetable of the Santa Fe ...

Security ElementsThe Digitrax Signaling System is organized around the concept of what we call "security elements", which are similar to what U.S. prototype railroads call "plants" or "interlockings". The Digitrax SE8C signal decoder displays aspects for up to 32 heads for 8 individual security elements (plants) using either a LocoNet Throttle or a computer with compatible software. When used with associated occupancy detectors and compatible software, the SE8C can be set up to protect the turnout with signals as shown by the example below. Note that trains can move from A to B, A to C, B to A or ...

Follow these simple instructions to determine the best location/s on your layout for installing your UR panels for the best possible infrared or radio reception. With LocoNet, you can use Infrared, Duplex Radio and Simplex radio individually or in any combination on your layout.You'll need to be able to observe whether your command station is receiving commands from the UR panels when you are installing infrared or radio receivers and transceivers. Your Digitrax command station makes it easy to determine when the system is receiving a signal and when it is not. You can observe the NET LED and the Track Status Indicator or your ...

How can I remotely monitor the input and output status of a section of the PM42 that is configured to act as a circuit breaker at a remote location? The final output stage, of each section, of the PM4 or PM42 is a DPDT relay. The contacts of this relay act in a similar fashion as the contacts of a DPDT toggle switch. These inputs and outputs can be monitored in a variety of ways. Three common monitoring devices are a LED (with appropriate resistor), a lamp (of the appropriate voltage), or an optical coupler (with appropriate resistor). The following ...

The answer to this question applies to all Empire Builder sets including Super Empire Builder XtraQ: I have just purchased a Super Empire Builder set. My expectations are for it to operate an N-Scale switching layout right now with future expansion to a larger N-Scale layout. I am a little confused as to which power supply I would need at this time. I am reading about power supplies and inline fuses, all of which is a little overwhelming to me as I am getting back into the hobby. Can you recommend which power supply will be better for me as ...

You can easily control sound units like the Keller SU1990 by using the function leads on Digitrax Decoders and DCC command station that can control decoder functions. These instructions for connecting a Keller Engineering Diesel Sound unit to Digitrax DH83FX & DH140 series decoders was writtne many years ago. Any modern Digitrax decoder with 4 function leads can be used. Equipment Needed:1) A Digitrax Throttle, Booster/Command Station or other DCC command station capable of controlling decoder function outputs.2) Any Digitrax decoder with at least 4 function leads will work here.3) The locomotive you wish to convert, be sure to check the ...

A speed table is a list of numbers, one number for each speed step. Many operators customize their locomotives by adjusting the CV's for Vstart (02), Vmid (06) and Vmax (05) to set the throttle response characteristics for each locomotive. This is known as a three-step speed table It is also possible to create a more complex speed table, either with 14 or 28 steps that specify the exact percentage of full power sent to the motor when the throttle is set to that speed. Speed tables can be set up for 14 or 28 speed steps, but not for ...

Many operators use a fast clock during operating sessions to simulate prototypical operations. Traditionally, the fast clock is on the wall in view of the train operators; it is set up to run at a faster than real time so that an operating session can simulate prototypical operation on a compressed time scale. LocoNet has its own networked fast clock for all Digitrax throttles connected to your system. The fast clock display is a 4 digit 12 or 24 Hour format clock. To display the fast clock simply press the CLOC c Key. The fast clock display will remain active while ...

Based upon a layout designed by the late, great John Armstrong which appears in the classic book, 101 Trackplans for Model Railroads [Kalmbach Publishing, 400-12012, still in print], this railroad combines different elements to offer varied model railroad operations. At the center right of the railroad is the Union Passenger Station. From this station, trains can operate out & back, which is to say that a passenger train leaves the station, goes out onto the circular main line and eventually comes back into the station after passing through the reverse loop. Another passenger train can operate point to point, meaning ...

Train detection and the related signaling can be a complicated affair. However, it becomes easier if you analyze things and break them down into their component blocks. The whole idea is to protect trains from each other, regulating their movements by the use of signals which tell train crews what to do or what to expect. Train detection identifies which segments of track are occupied by a train. For the real railroads, track detection sections can be very short (such as at track junctions) or very long (such as in rural environments). Train speed and frequency of trains are also ...

I am now constructing an N-Scale layout with Digitrax DCC system. I know SE8C and two-heads signal mast supplied by your company are applicable for a entry signal mast for the both of main and siding (branch) lines. However, I don't know how the signal mast is used in the case of "more than two" siding lines. For example, the next picture was taken in Powder River Basin (Converse Jct.) in Wyoming State. TS, Japan In this picture, some two-heads signal (mast) can be seen. In every signal mast, the top signal head will be for a main line. But, ...

I have a 4x8 H0 scale layout. I'm 13 years old and REALLY thinking about switching to DCC, I need to know really fast because I want to ask my parents to get it for Christmas.You wouldn't know by looking at those who edit the Tech Support Depot, but there actually was a time when we too were thirteen, and just starting out in model railroading. In many ways, we still are thirteen years old; we just can't move as fast. Consider this photograph from our youth: This little bit of ancient model railroad history dates back to the 1950's, ...

DCS240 FAQ I’m getting a “StealZap” or message on my DT402 rev 2 throttle. What is this? This is a feature that helps prevent having the same address selected on multiple throttles and creating unexpected operations. When you steal you are truly stealing control of the locomotive instead of sharing it as was the case before the DCS240 and DT402 R2 firmware were released. When using a DT402 R2 throttle with an Advanced Command Station featuring expanded slots, each throttle ID is associated with the Loco Addresses it has selected. When you select a Loco that is selected on ...

Digitrax decoders have outputs that can control lamps and other on/off devices installed in your locomotive. These are called functions. Functions are things like: lamps, sound units, smoke units, etc. All Digitrax decoders are equipped with two or more function outputs that are used to turn functions on and off.Decoder function outputs can be:1. Leads (wires) attached to the decoder that are used to hook up external functions. See Table I below for wire color codes used on Digitrax decoders.or2. Pre-wired function outputs that hook up by just plugging in the decoder. This is the case for decoders that ...

Decibel measurements on SDH164D Digitrax Sound Sound level is a logarithmic measure of the effective sound pressure of a sound relative to a reference value. It is measured in decibels (dB) above a standard reference level. The commonly used "zero" reference sound pressure in air is 20 µPa RMS, which is usually considered the threshold of human hearing (at 1 kHz). Examples of some Loudness rating in both Pa and dB Hearing damage (over long-term exposure, need not be continuous) 0.356 Pa 85 dB Handheld electric mixer 65 dB TV (set at home level) at ...
